One little slip and any standard knife will be lost to the murky depths. But the Swedish artisans at 130-year-old Morakniv have the answer: a precision-crafted knife equipped with a cork handle that’s both buoyant and beautiful. Dozens of independent hand operations go into each knife’s construction – from forming the moisture-impervious polymer-core handle to forging the razor-edged stainless blade. And if you do happen to drop it overboard, the lime green polymer sheath is easy to spot in dark water.
